<span>Sr + O2--->2SrO</span><span>is the right answer</span>

<span>The correct answer would be the second option. It is the reaction Sr + O2 = 2SrO that is not balanced correctly. To be able to say that an equation is balanced, it should be that the number of each atom in the reactant and the product side is equal. As we can see, at the reactant side there is only one Sr while in the product there are 2 Sr atoms.
